Delphi vs Java: What are the differences?

Introduction

Delphi and Java are both popular programming languages used for building software applications. While they share some similarities, there are key differences that set them apart.

Syntax: Delphi uses a Pascal-like syntax, which is more readable and easier to understand for beginners. On the other hand, Java uses a C-like syntax, which is more complex and requires a deeper understanding of programming concepts.
Platform Independence: Java is designed to be platform-independent, meaning that a Java program can run on any operating system that has a Java Virtual Machine (JVM) installed. Delphi, on the other hand, is primarily designed for Windows-based systems, although there are third-party tools that enable cross-platform development.
Development Environment: Delphi has its own integrated development environment (IDE) called RAD Studio, which provides a comprehensive set of tools for building Windows applications. Java, on the other hand, has multiple IDE options like Eclipse and IntelliJ IDEA.
Garbage Collection: Java has a built-in garbage collector that automatically manages memory allocation and deallocation, making it easier to write bug-free code. Delphi, on the other hand, requires manual memory management, which can be more challenging and prone to memory leaks if not done correctly.
Community and Libraries: Java has a larger and more active community, with a vast number of libraries and frameworks available for various purposes. Delphi, on the other hand, has a smaller community and fewer libraries available, especially for newer technologies and platforms.
Native Code Execution: Delphi compiles code into native machine code, resulting in faster execution speed compared to Java, which relies on the JVM to execute bytecode. This makes Delphi suitable for performance-critical applications.

In summary, Delphi and Java differ in their syntax, platform independence, development environments, memory management, community support, and native code execution. These differences should be considered when choosing a programming language for a specific project or application.

Decided

C# and .Net were obvious choices for us at LiveTiles given our investment in the Microsoft ecosystem. It enabled us to harness of the .Net framework to build ASP.Net MVC, WebAPI, and Serverless applications very easily. Coupled with the high productivity of Visual Studio, it's the native tongue of Microsoft technology.

Building cool things on the internet 🛠️ at Stream

Sep 5, 2019

Review

I work at Stream and I'm immensely proud of what our team is working on here at the company. Most recently, we announced our Android SDK accompanied by an extensive tutorial for Java and Kotlin. The tutorial covers just about everything you need to know when it comes to using our Android SDK for Stream Chat. The Android SDK touches many features offered by Stream Chat – more specifically, typing status, read state, file uploads, threads, reactions, editing messages, and commands. Head over to https://getstream.io/tutorials/android-chat/ and give it a whirl!

Decided

When developing a new blockchain, we as a team chose Go lang over Java and other candidates, due to Go being (a) natively suited to concurrency - there are primitives in the language itself (goroutines, channels) that really help with reasoning about concurrency (b) super fast - build time, running, testing are all much faster that Java, this gives a far superior developer experience (c) shorter and stricter than Java - code is much shorter (less verbose), and there is usually one good way to do things, and even the code formatter that is bundled with Go is very opinionated - over a short time this makes reading other people's code far smoother than having to deal with different styles.

You should be aware that Go presently (v1.13) lacks Generics.

Detailed Comparison

Java	Delphi
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!	It is an integrated development environment (IDE) for rapid application development of desktop, mobile, web, and console software.

What are some alternatives to Java, Delphi?

JavaScript

JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.

Python

Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.

PHP

Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.

Ruby

Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

Golang

Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.

HTML5

HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.

C#

C# (pronounced "See Sharp") is a simple, modern, object-oriented, and type-safe programming language. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers.

PhpStorm

PhpStorm is a PHP IDE which keeps up with latest PHP & web languages trends, integrates a variety of modern tools, and brings even more extensibility with support for major PHP frameworks.

IntelliJ IDEA

Out of the box, IntelliJ IDEA provides a comprehensive feature set including tools and integrations with the most important modern technologies and frameworks for enterprise and web development with Java, Scala, Groovy and other languages.

Scala

Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.
